A whining supercharger (a.k.a. “blower,” for the way it provides an engine with extra air) has long been associated with the wild rides of drag racers, street rodders, and Mad Max. The latest blowers, such as Eaton’s TVS R1320 supercharger, are changing that perception. The TVS (Twin Vortices Series) is efficient enough for a Porsche hybrid, hushed enough for a Jag, and powerful enough for the Corvette ZR1. We cut into an Audi 3.0-liter V-6’s TVS to see what makes it the quiet powerhouse it is.
